C454 black prints light and also shadowy text

[positiveg]

Hi guys need some assistance please
We've changed the drum, added new black developer , change the cleaning blade for the IBT
but still no look
please check images. I was browsing the forum and I see something about toner, that's the only thing I haven't changed. But we also cleaned the lens as well.

OK I'll try that.

Also when I ran the test on all the colours only the black showed terribly

Find the post by the genius blackcat4866:
C452 Dumpster to the Rescu(r)e!?!

The internal test might be useful too. Post scans not pictures if possible.

Did you replace the black developer unit or just replace the developer powder?

If wanding the laser slit glasses does not help, you'll need a cyan and black drums. The test patterns help diagnosing immensely. =^..^=
